Answer: -7 1/2
Step-by-step explanation:
The required number would be -3/10.which is the correct answer would be option (B).
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.
We have been given that two-thirds of a number is equal to a negative one-fifth.
Let the number would be x
According to the given question, the required solution would be as:
⇒ (2/3)x = -1/5
Divided by (2/3) both sides of the above equation,
⇒ (2/3)x/ (2/3) = (-1/5)/(2/3)
⇒ x = (-1/5)/(2/3)
Reciprocal the term in the numerator,
⇒ x = (-1/5) × (3/2)
Apply the multiplication operation, and we get
⇒ x = -3/10
Therefore, the required number would be -3/10.
Hence, the correct answer would be option (B).

24 feet, 30 feet, 30 feet
26 feet, 26 feet, 26 feet
30 feet, 48 feet, 48 feet
Answer:
24 feet, 24 feet, 30 feet
Step-by-step explanation:
edge 2020
The given perimeter of 108 feet, and length of the longer side of 30 feet,
gives the following length of the other sides;
24 feet, 24 feet, 30 feetWhich method can be used to find the lengths of the sides?A kite has two pairs of adjacent sides having equal length
Let x represent the length of one of the shorter sides, we have;
The perimeter of the kite = 2 × x + 2 × 30 = 108Which gives;
x = (108 - 2 × 30) ÷ 2 = 24
The length of one of the short side, x = 24 feet
The kite has 2 sides of length 24 feet and 2 sides of length 30 feet
The lengths of the other sides are therefore;

Hey there! Let's answer each part of this question in order.
Part aIf Pedro withdrew [tex]\$35[/tex] per week, his change in balance could be represented as [tex]-35x[/tex] since [tex]x[/tex] is the number of weeks. Add this to his initial balance of [tex]\$710[/tex] to get the first answer:
[tex]\huge\boxed{710-35x}[/tex]
Part bThe same concepts can be applied to solve the next part. Maria started off with [tex]\$570[/tex] in her account and withdrew [tex]\$25[/tex] each week. Apply the same process from the first part to get the second answer:
[tex]\huge\boxed{570-25x}[/tex]
Part cWrite an equationFor the last part, we need to find the value of [tex]x[/tex] that makes the expressions we made in the first two parts equal to each other, so start by making them into an equation.
[tex]\huge\boxed{710-35x=570-25x}[/tex]
Solve the equationNow we need to solve this equation. Start by bringing the constants to the right and the variables to the left.
Keep in mind that when you move a term to the other side of the equation, you need to change its sign, as you are adding or subtracting the same number from both sides of the equation.
[tex]\begin{aligned}710-35x&=570-25x\\-35x&=570-25x-710\\-35x+25x&=570-710\end{aligned}[/tex]
Now, combine the like terms with addition and subtraction.
[tex]\begin{aligned}-35x+25x&=570-710\\-10x&=-140\end{aligned}[/tex]
Finally, divide both sides of the equation by [tex]-10[/tex] to fully isolate the variable and find the final answer.
[tex]\begin{aligned}-10x&=-140\\x&=14\ \text{(weeks)}\end{aligned}[/tex]
[tex]\huge\boxed{14\ \text{weeks}}[/tex]
Check your answerWe can also check our answer by substituting the final answer back into each expression, simplifying, and making sure the answers are equal.
[tex]\begin{array}{l|l}710-35x&570-25x\\710-35*14&570-25*14\\710-490&570-350\\220&220\end{array}[/tex]
Since the expressions are equivalent, we know that Pedro's balance is the same as Maria's balance after [tex]14[/tex] weeks.

Write an equation to represent the tape diagram.
Find the value of p that makes the equation true.
Answer:
6p =120
Step-by-step explanation:
well the p's are very close together in a sense that we are going to multiply instead of add because they the p's would have space in between
6 * 20 = 120
so p= 20
choose A
and P=20
6p is equal to 6×20
to get P, do 120÷6

1/12 of their squad are suspended, some of the squad are injured, and this leaves only 14 players to choose a team from,
What fraction of the squad are injured?
Answer:
1/3.
Step-by-step explanation
1/12 * 24 = 2 players suspended leaving 22 players.
So the number injured = 22 - 14 = 8.
Fraction injured = 8/24 = 1/3.

The Circle Problem Draw a circle.You have only 3 lines. Divide the circle into 7 pieces.
In your own words, explain how to solve this problem. To attain maximum credit please include any websites used for references. Your reflection should include complete sentences and paragraphs.
Answer:
Draw a x then place a horizontal line to cut the highest quarter piece in half
A circle with 7 pieces is given below.
What is a circle?A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle.
And the general formula of the circle,
(x – h)²+ (y - k)² = r²,
where (h, k) is the center and r is the radius of the circle.
Here is one way to divide a circle into 7 pieces using only 3 lines:
Draw a horizontal line across the middle of the circle to create two equal halves.
Draw a vertical line that intersects the horizontal line at the center of the circle.
Draw a diagonal line from the top of the circle to the bottom, passing through the center point.
This should create 7 pieces in the circle: two halves, four quarters, and one central piece that is shaped like a kite.
Therefore, the diagram of the image is given below.

Your total cost C to skate at Skate Days is a $2 skate rental plus an additional $3.25 for each hour Chat
you skate.
Write a function rule to represent the situation.
19
Is this situation continuous or discrete? Explain your reasoning.
Create a sign that Skate Days can display at the counter that tells people how much it will cost
for each hour they skate (include 1-5 hours on your sign)
Skate City has free skate rental but charges $4 for each hour.
Which skating rink would you choose to go to?
Why did you make that choice? Use mathematical reasoning to support your answer. Lo
Answer:
The cost is a fixed $2, plus $3.25 for any additional hour.
Then if you rent it for x hours, the cost is:
c(x) = $2 + $3.25*x
Is this situation continuous or discrete?
Yes, it is discrete, because x is "the number of hours"
so if you rent it for 1.30 hours, they will say "ok, this is equivalent to two hours".
This means that while the values of x are continuous, the possible costs are:
{$2, $2 + $3.25, $2 + 2*$3.25, ....}
Which is a discrete set.
Then the sign for 1 to 5 hours will be:
1 hour ---------- $2 + $3.25 = $5.25
2 hours -------- $2 + 2*$3.25 = $8.50
3 hours--------- $2 + 3*$3.25 = $11.75
4 hours--------- $2 + 4*$3.25 = $15
5 hours -------- $2 + 5*$3.25 = $18.25
In the other park the cost is only $4 for each hour (no fixed cost) then the total cost for x hours is:
c(x) = $4*x
Now, which option is better?
If we look at the costs for different numbers of hours for this other equation, we have:
1 hour ----- $4
2 hours ---- 2*$4 = $8
3 hours ----- 3*$4 = $12
4 hours ------ 4*$4 = $16
Then: if you want to skate 2 hours or less, Skate City is cheaper, if you want to skate more than that, kate Days is cheaper.
This happens because the first one has a smaller slope, meaning that is larger at first, but as x grows the price does not grow as much as in Skate City

By applying sine rule in the given triangle,
Sin(55°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
0.819152 = [tex]\frac{\text{RQ}}{\text{PR}}[/tex]
